UNIX for Dummies Questions & Answers

Hi Guys,
Can anyone of you please tell me how to use a variable inside a awk command.

For ex - if am printing the third column with respect to a pattern with delimiter ~

Code:

awk -F~ '$3=="pattern"' <file name>

- This works,

Now here I have a set of patterns in a file and I want to put it in the loop. But awk does nt recognize it.

Code:

awk -F~ '$3=="$line"' <file name>

- This does nt work,
where $line = pattern

Thanks in advance,

Regards,
Abhishek S.
